In the present invention, a communication unit (20) communicates with a plurality of management subjects. An operation mode determination unit (24) determines whether or not the system sate of the plurality of management subjects as a whole satisfies pre-defined conditions on the basis of information indicating the state of each management subject received by the communication unit (20). When it has been determined by the operation mode determination unit (24) that the system state satisfies the pre-defined conditions, a network communication mode switching unit (25), a communication parameter alteration unit (26), an apparatus communication condition setting unit (27), a state-value-acquisition-cycle setting unit (28), and a communication pattern setting unit (29) adjust the communication state of the communication unit (20) in accordance with the processing performance of the device in question and the system state. |
